On June 18, 2025, at the invitation of Researcher Dai Xingliang from Zhejiang University, Professor Liberato Manna from the Italian Institute of Technology visited Wenzhou Research Institute of Zhejiang University and Wenzhou Zinc Core Titanium Crystal Technology Co., LTD. Professor Liberato Manna is an internationally renowned expert in perovskite luminescent materials. He serves as the director of the Department of Nanochemistry at the Italian Institute of Technology and concurrently holds the position of associate editor of the internationally renowned academic journal "Nano Letters". More than 320 academic papers have been published in journals such as Science, Nature Energy, Nature Materials and JACS, with a total citation count of over 50,000 times. Professor Liberato Manna ranked 24th among the top 100 chemists worldwide during the decade from 2000 to 2010 as statistically analyzed by Thomson Reuters.

Professor Liberato Manna gave a related research report on the theme of "Halide perovskite nanocrystals" (Halide Perovskite nanocrystals), sharing the latest progress of his team in the preparation of perovskite nanocrystals, the construction of heterostructures and the research on luminescence mechanisms. And had a lively discussion and in-depth exchange with the teachers and students present, and gave patient and detailed answers to the questions raised by everyone.

After the meeting, Professor Liberato Manna visited the research and development center of new optoelectronic materials and our company on the spot. He visited our company's research and development laboratory and the perovskite quantum dot production line, and personally experienced related products such as perovskite quantum dot liquid crystal display and health lighting. Professor Liberato Manna highly praised the all-solid-state perovskite quantum dot technology and related products. He believed that this technology not only broke through the stability problem that plagued the field of perovskite materials, but also demonstrated industrialization advantages such as low manufacturing cost, strong product compatibility, and high batch repeatability. It is believed that the Chinese team is at the forefront of the world in promoting the industrialization of perovskite luminescent quantum dots.

Professor Liberato Manna also had a special exchange with the R&D team on the performance optimization and luminescence mechanism of perovskite quantum dots. Both sides conducted a detailed and in-depth discussion on the optimization of perovskite quantum dot ligands and heteroepitaxial growth technology, etc.
